The information about the patch mentioned in the Windows 7 and Games thread
The patch seems to have originally been made for Pentium III processors, and is an old patch by now, but consider that the game was originally made for a Pentium 100.
The patch seems to be a self-extracting .exe file from year 2000.
You first install the game, then run the patch to extract the files in the patch and overwrite files in the game folder with those in the patch.
You may need to install the game using compatibility mode (right-click the installer on the game CD, change compatibility, Save changes, Exit, then run the installer).
